Multi-Directional Louver System

Clearly Daylighting Factor is not a sufficient metric for louvers daylighting analysis which is evident in comparing the results of simulations using Diva3 for Grasshopper focused on changes of DF with Sefaira using ASE and sDA. Great that DIVA added the features of Diva for Rhino to Diva for Grasshopper in version 4! And not clear to me why still some software use only DF in their daylighting analysis. To find more about different daylighting metrics you may read a collaborative research paper here which was presented in Qatar ASHRAE conference.
